costa of the hindwing is very distinct and the part of the forewing covering it is therefore somewhat lobate. 
— aristarchus Fruhst. (155 e) shows this scent-basin still more intensely covered with quite black hair, and the aristarchus. 
corresponding scent-brush on the forewing above is very much enlarged. Besides the blue colour above is 
somewhat lighter than in typical anysides. From Bazilan. — In poliorketes Fruhst.. from the Southern Philip- -poliorkctcs. 
pines, the hairing of the androconial spot is yellow. 
50. Genus: Caniena Hew. (Pratapa Mr.). 
As has already been mentioned in the preceding genera, the differences of these genera are very sub¬ 
tile and rather unreliable. Above all, generic differences ought not to be founded on scent-organs, nor does the 
neuration by the different subcostal system offer any reliable means of distinction; and just as uncertain is 
also the separation from the following genus Tajuria. The most distinctive mark is offered by the habitus; 
the pointed forewing, the oblong-oval hindwing with small scarred impressions at the base of the subcostal, the 
very long hind-margin of the hindwing which shows 2 small tails and an anal lobe, and above all the very strong- 
thorax. As the chief character always the 3-branched subcostal is stated. Description of the genus in Yol. I. p. 261. 
C. ctesia Hew. (155 d). Since the publication of my treatise in Vol. I, where a Chinese specimen was ctesia. 
figured as ctesia, Fruhstorfer has separated the Chinese form as agalla. In the latter species, to which conse- agalla. 
quently the figure in Vol. I. pi. 72 c would belong, the black cell-end spot on the forewing above (and also the 
marking of the under surface) is more strongly developed. The typical ctesia come from North India. - In 
cakravasti Fruhst. (155 d), from Formosa, the discal spot on the forewing is not much larger, but the forewing cakravasti . 
has a broader black margin, and the under surface which in agalla is more silvery grey and yellowish-brown in 
ctesia, is bluish-black in cakravasti, according to Fruhstorfer. The are said to be common in Sikkim; in 
China they are decidedly rare, nor do they seem to be very numerous in Formosa. 
C. icetas Hew. (Vol. I, pi. 72 c). This imago has already been dealt with in the palearctic part Vol. I, icelas. 
p. 261. It was described from the palearctic part of Kashmir, but it also occurs, even in greater numbers, in 
the Indian part (Kulu), also near Simla, in Masuri. and even in Darjeeling. 
C. deva Mr. (155 b, c). Like in icetas the upper surface strongly recalls a Tajuria longinus, but it has cleva . 
not the narrow hindwing of Tajuria. The wings being above very broadly margined with black exhibit in the G a 
very bright deep blue colour; in the $ a slight lilac reflection covers the blue; the under surface of typical deva 
is greyish-white in the^; they are described from South India (Canara). angada Fruhst. (155 c) is the form angada, 
from North India, the upper surface, particularly in the hindmarginal area of the hindwing is somewhat lighter, 
the upper surface of the not so very lustrous; under surface almost white. devana Drc. (155 c) is much devana. 
larger, the black marginal band particularly in the region of the anal angle of the forewing much broader. North 
Borneo. —- Fruhstorfer separates from this distinctly different form the 9$ from South Borneo as devadatta devadaita. 
(155 c as devadetta ) with a very sooty upper surface, where the black powdering is particularly extensive in the 
costal area of the hindwing. cartena Fruhst. (155 c as carthena ) has above in the G and ? a narrower black cartena. 
margin which is more distinctly separated from the blue ground-colour, and the under surface is of a dingy 
earth-colour; from West Java. - From this form the specimens from East Java (from the district of Lawang) 
are separated as methara Fruhst. which are much darker than cartena, with much broader black margins of methara. 
the forewing, almost extending to the cell; the hindwing is also darker. - lila Mr., from Assam and East Bengal, lila. 
is rather small, with less gloss than in typical deva , but with a slight violet reflection on the blue. — Larva 
of the shape of a rather stout woodlouse, grey, so similar to the colour of the leaves of its food-plant (Loranthus 
tomentosa) that in changing the food the larvae are easily thrown away with the other food. Pupa whitish- 
green, with fine brown markings, somewhat similar to that of Creon cleobis (Davidson, Bell, and Aitken). 
— The imago is always met singly, but in some places not very rarely. 
C. ister Hero. ( = carmentalis Nic.) (155 b) is much smaller - than the preceding ones, otherwise very ister. 
similar to deva , and it was also confounded with cleobis. Forewing 1 blue with a dark brown apical half; apex 
of hindwing dark yellowish-brown. Under surface reddish yellowish-brown with an arcuate stripe of white- 
edged comma-spots before the marginal area. In the typical specimens (from Assam) the blue colour is in the 
$ hindwing confined upon the central part of the wing, whilst the hindwing beneath shows a rather small orange- 
red spot before the black dots in the anal region. —- yasa Fruhst., from Nias, has a lighter blue upper surface yasa. 
with scarcely half as broad marginal black, the anal orange spots on the hindwing beneath being more than 
twice as large. — cretheus Nic. (155 b) is larger; the costal margin is broad, the distal margin narrow black; cretheus. 
otherwise very similar to yasa ; from West Java. In calculis Drc. (155 b), from Borneo, also the black colour calculis. 
of the apical region of the forewing is much narrower. — ecphantus Fruhst. (155 b), from the surroundings ecphantus. 
of Lawang in East Java, is small, above darker metallic blue, the black margin of the hindwing hardly broader 
than in the Nias-form yasa; the anal orange spots of the hindwing beneath are only small. — cameria Nic., cameria. 
being unknown to me, is a very similar form from Bua-Kraeng; it seems to represent ister in Celebes, but it may 
also be a distinct species.
